FORMER OR DIE FOR MAKING'I-IOLLOW TILES.

Specification of Letters Patent. 7

Patented July I7, 1917.

Application filed March 21, 1917. v Serial No. 156,332.

To all whom it may concern:

Be it known that I, WILLIAM L. HANLEY, Jr, a citizen of the UnitedStates, and resident of Bradford,Pennsylvania, have invented certain newand useful Improvements in Former-s or Dies for Making Hollow Tiles, ofwhich the following is a specification.

The invention is a former or die for making hollow tiles and consists inthe features and combination and arrangement of parts hereinafterdescribed and pointed out in the claims.

In the accompanying drawings:

Figure l is a front view of the die or former.

Fig. 2 is a side view, and

Fig. 3 is a sectional view.

The former or die consists of an outer frame 1 havingan open interior,the frame consisting of a base member and a rim flange or portion 2arranged around the edge of the opening in the base member and extendingperpendicular to said base member. Within the opening provided by thiswall or rim, former or die blocks 3 are supported in any suitablemanner, these being positioned separated from each other and alsoseparated from the surrounding wall or rim of the die by a space equalto the thickness that the tile isto be. While the supporting means forthese interior blocks or dies may assume various forms I show themattached to posts or arms 4: extending from cross bars 5 which are heldto the base plate of the die by suitable connections or posts 6. Theinterior die blocks rests upon these posts f and are secured thereto bybolts 7 screwthreaded into sockets in the posts, washers 8 beingprovided between the heads of the bolts and the outer faces of the dieblocks. The openings through the die blocks for rereceiving the boltsare slightly larger than said bolts, so that the blocks can be adjusted,in all directions toward and from each other and consequently toward andfrom the surrounding wall of the main part of the die or the blocks maybe set at a slight angle to each other and to the adjacent portion ofthe surroundingwall of the main part of the die or former. By this meansshould the flow of material be found to be too fast at one point theblock can be adjusted to contract the space through which this rapidflow takes place, so as to retard it and this adjustment can take placeboth as between the two blocks and also between each block and thesurroundinggwall of the die. I

In order to provide the outer faces of the aollow tiles with grooves toreceive plaster, cement or the like I provide'a number of bolts 9 only afew of which need be shown extending through the rim or wall of the dieand into the interior space, the inner ends of these bolts, which ofcourse are threaded are exposed in this threaded condition, so that asthe material passes these projecting threaded ends the channels will beformed in the outer faces of the hollow tile material and these channelswill have minor channels or grooves in their faces resulting from thepassage of the material against the threads of the exposed ends of thebolts'and these minor channelswill serve to receive the plaster orcement and lock the same in the main grooves or channels of the tile. 7Furthermore, these bolts extending through the wall of the die to theinterior space thereof may be made to perform another function, namely,that of adjusting or vcontrolling the flow of the material through thespaces between the main part of the die andthe inner die blocks and ifthe material isfound to be flowing too fast at any point the bolt orbolts at that point are adjusted inwardly and thus offer greater resistance because of the reduction of the space to the flow of thematerial and thus the flow can be regulated throughout the entireperimeter or edge of the die. The hollow tiles will be formed with atransverse division wall because of the fact that the two interior dieblocks are separated from each other by a space through which thematerial is forced. Any suitable means may be provided for forcing thematerial from the rear of the block, that is, the side upon which theframe-work and posts are located through the same to the front.

The die blocks may be tapered toward the rear as indicated to provideflaring openings between themselves and also between themselves and thesurrounding wall of the main parts or frame of the die to receive thematcrial and direct it forwardly. The screw conveyer which forces thematerial through the die may work in a suitable cylinder, against thefront end of which the die is fixed.

I provide wearing plates or liners, as shown at a, on the interior faceof the die I this can be removed and replaced without removing-the=-rear 'wear plate or section.

" What "I claim is 2 I I 1. In combinationin a die or former for hollowtiles, maindie portion having an open interiorfa die block within theopening and'bolts'closelyset together and pass ing'through the main partof the die with their fends projecting 'into the opening, saidboltsbeinglo'cated at different points along and opposite a side face'of'the dieblock independently adjustable and adapted to form thegrooves in the outer face of the material expressed. through the die;substantially as described.

2. In combination in a die-or former for hollowtiles, a main die portionhaving an open-interior, a'die block withinthe opening and'bolts passingthrough themain part of the"die"'with their" ends projecting into theopening, said bolts being independently adjustable andadapted to formthe grooves in the outer face of the material expressed through the die,said bolts having their expose'djinner ends provided with lateralprojection's'to form minor grooves in the main grooves,"substant1ally asdescribed.

? combination 1n a'die or former for (topiesliof this patent may-beobtained for hollow tiles, a main portion having an open interior, a dieblock within the opening and bolts closely set together and extendingthrough the wall of the main die and having their inner threaded endsprojecting into the opening to form grooves in the face of the materialwith minor grooves in the main grooves resulting from the screw threads,substantially as described.

4:. In combination in a die or former a main portion having an interioropening, a die block within the opening having faces substantiallyparallel with faces on theinterior of the main portion, said inner dieblock being adjustable about its axis into different angular positions,bolts closely set together and extending through the main die and havingtheir inner ends exposed opposite the face of the inner dieto formgrooves in the material, said-bolts being in dependently adjustabletoward and-from the inner die.

5. In combination, in a die or former for hollow tiles, a main diehaving fiat inner faces, an inner die block within the opening of themain die having fiat faces substantially parallel with the inner facesof the main die, said inner die being adjustable laterally andangularlyto vary the position of its flat faces in respect to the'flatfaces of the outer die and bolts extending through the outer die anddisposed at different points along a flat face thereof, said boltshaving broad inner ends to form channels in the outer face of the tile,the bolts disposed along one face being adjustable relative to eachother to regulate the flow of material between said face andthe opposingface of the inner die, substantially as described.
